What Is the GROL and Why It Matters for Radio Professionals
The GROL, or General Radiotelephone Operator License, is issued by the FCC and authorizes holders to adjust, maintain, and repair radio transmitting equipment at FCC-licensed stations. It combines two examination elements: Element 1 (Marine Radio Operator Permit) and Element 3 (General Radiotelephone), though many candidates pursue Element 3 directly if they already hold Element 1. The GROL is required for technicians who service land mobile radio systems, aviation radio equipment, and certain maritime electronics.
Who Needs a GROL License
Any technician who makes internal adjustments to FCC-licensed transmitters operating on frequencies where a licensed operator is required must hold a GROL. This includes avionics repair technicians, two-way radio shop technicians, and engineers maintaining broadcast transmitter equipment at commercial radio and television stations.
GROL License Cost
The cost to obtain a GROL license is relatively low compared to other professional certifications. Fees are paid to the testing center, not the FCC directly.
Since the FCC GROL license does not expire and requires no renewal fees, your initial investment of ~$100 provides lifetime career benefits.
